threzul Mounted against the shoulder 10, is an apertured disk 11, having that face thereof out of contact with said shoulder 10, countersunk as at 12 to form a concaved recess. Mounted in the contracted end (3 of the housing 5, is a packing gland 13, formed with a concaved recess 13*. The packing gland 13 is peripherally threaded and engages with the threads 7. Inter-posed between the disk 11 and the gland 13, and mounted in the recesses 12, 13 is a packing 1; for an adjustable valve stem 15, the latter extending through the contracted end 6 into the larger portion of the housing 5, as well as projecting through the disk 11 and gland 13. The stem 15 projects outwardly with respect to the reduced end 6 of'the housing 5 and has its outer end squared as ht 15" and further formed with a cylindrical threaded extension 15". Mounted upon the squared portion 1?) of the stem 15 is a hand wheel 16 substantially in the form of what may be termed a four pointed star. Positioned upon the extension 15" is a nut 15, which engages with the wheel 16 for maintaining it upon the stem 15. The squared portion 15 ot' the stem 15 prevents the wheel 16 from turning independently of the stem.

The outer face of the wheel 16 is provided with indications 16", 16 and 16 and 16. These indications are located at the respective points of the wheel and mark various positions of the valves from closed to full opening.

The cylindrical housing, in proximity to its reduced end, has arranged therein an integral partition 17, forming a fluid chamber 20, and said partition 17 centrally thereof is provided with an opening 18, for establishing communication between the compartment 17", formed forwardly of the partition 17 and the fluid chamber 20.

The opening 18 is closedthrough the medium of a fluid supply valve 19, the latter being conical in contour and formed integral with the forward end of the stem 15. The. base of the valve 19 is of less diameter than the diameter of the forward end of the stem 15, whereby a flange or shoulder 19" is provided which when the valve stem 15 is shifted to the limit of its forward movement, abuts against the partition 17 whereby the opening 18 is closed.

The housing 5 is provided with an inclined passage 21, which establishes communication between the fluid chamber 20 and a fluid inlet nipple 22. The nipple 22 is peripherally threaded andengaging with the threads of the nipple 22 is a flanged collar 23, for coupling to the nipple a fluid supply pipe 2-1. The housing 5 diametrically opposite the nipple 22 is provided with an oil inlet nipple 25, which is peripherally threaded, and engaging with the threads of the nipple 25, is a flanged collar 26 for coupling an oil supply pipe 27. By coupling the pipes 21, '27 to the nipples 22, 25, in the manner as stated, the housing 5, can be adjusted to various inclinations or to a vertical or horizontal position.

Mounted in the housing 5, at the larger end thereof, is the reduced portion 27 of a stem guide and seat member. The larger portion of said member is indicated at 28 and provides a shoulder 29 which abuts against the housing The reduced portion 27 of said member extends to a point in close proximity to the partition 17 and the said reduced portion 27 is peripherally threaded for engagement with the threads 30 of the inner face of the housing 5, whereby said member is detachably connected to the said housing 5. The reduced portion 27 at its inner end is provided with an annular pocket 31, which opens into a longitudinally extending passage 32, the latter communicating with an inclined port 33, which opens into a fluid chamber 31, formed in the enlarged portion 28 of the stem guide and seat member. The reduced portion 27 of the stem guide and seat member is formed centrally with an oil receiving chamber 35, which communicates with an inclined passage 36 formed in said reduced portion 27. The housing 5 is formed with an inclined port 37, the latter opening at one end into the oil inlet nipple 25, and at its other end registering with the passage 36. Arranged centrally of the reduced portion 27 of the stem guide and seat member, and extending from the chamber 35 to the inner terminus of said reduced portion 27 is a longitudinal bore 38, in which is mounted an auxiliary valve stem 39, which is formed integral with the forward end of the valve 19, and normally projects into and is of 'less diameter than said oil receiving chamber 35. The auxiliary stem 3-) terminates in a eoni -al needle valve 10, which engages a valve seat ell, the latter being formed by providing the forward terminus of the reduced portion 27 of the stem guide and seat member with a tapering bore, the latter connnunicating with the chamber 35, and the base of the valve -10 is of less diameter than the forward terminus of the stem 39.

The enlarged portion.28 of the combined stem guide and seat member is provided withan annular recess to form the fluid chamber 31,- and by forming the annular recess, a centrally disposed tubular member 41 is left, having a longitudinally extending and centrally disposed bore -12 which forms a continuation of the valve seat 44 and into which is adapted to extend the forward end of the valve 40. The member 41, at its forward end is peripherally grooved, as at 43, for a purpose to be presently referred to. The inner faceof the enlarged portion 28 of the stem gulde and seat ,mem-

' portion 63 on the rearward movement of the her is provided with threads -15. Y 1

Extending} into the enlarged portion 28 of the stem guide and seat member is a cylindrical member-A6, having its inner face tapering for a portion of its length asat 47,. forming one wall of ,the chamber 3%. A portion of the inner faceof the member 46, in longitudinal section, is rounded as at 48, the tapeiungportron 47 merging. 1n

the rounded portion 48, which latter op-,

oses the roove l3 and rovides in con-,

nection with said-groove a3, an annular outlet 49 'for the fluid chamber 34, the

outlet lflbeingicurved in longitudinal section, The bore;of. the member, 46, that is that 'portionprojecting forwardly. from the rounded portion f 48, as indicated at .50 is smooth and of the same diameter throughout and at its outer end formed with threads 51, and secured in the member 46, intermediate the ends of the portion 50 of the inner face of said memberl6, is a par tltlOIl 52 formed with a series of ports53,

which incline toward the center of theouter face of the partition 52. The partition 52,

in connection with the members 41,46,131'0- vides a mixing chamber 53 for the Oll and fluid, the oil being. supplied. into the 1chamber 53 by the bore or passagedQ, the fluid being supplied by the passage49.

The member 46, intermediate its ends, is

provided witha peripheral collar 54, which abuts against. .th e forward end of the stem guide and seat member, and said member 46 is further provldcd "with peripheral; threadswhich engage with thethreads 4:5,

whercbvthe member 46 is detachably connected to the stem guide and seat member, The member -l6 1s turthermore provldedg withperipheral threads 55 for connecting:

the forward end of if it be desired. Extending in the v 7, member 46. and spaced from thepartition the burner to a support,

52, aswell as engaging with-{the threads. 51, 1s acouphng member 56 formed wlth a tapering recess 57 and a socket 58,{which communicates with the recess 57 The wall of the socket 58 isthreaded and engaging with said threads is the inner peripherally threaded end of a nozzle 59, the inner end of the latter being beveled as at 60, forming a continuation ofthewall of the recess 57-.)

' The nozzle 59 is provided with a passage 61,

which communicates with a taperingoutlet 62, at the forward endof the nozzle 59; The a member 56 is utilized. forcouplingf the noz zle 59 to thefmember 46. Y

The valve stem 15, adjacent the valve 19' is enlarged-as at 63, and threaded for engagement with the threads 9 of the reduced end 6 of the housing 5. WVhen the burner is set up, the enlarged portion 63 of thevalve forward end of the,

' ing air in: a whirling manner to saidiohamher, and a pair of valvular elements operating in unison and controlling the supply of stem 15 preventsthe entire withdrawal of" said stem due to the. fact that said enlarged valve stem; will abut against the disk 10,.

under such conditionsarresting further. rearward movement of the stem 15'. By

- thisarrangementliability' ofburning of the operator is prevented. I v :The flu1d',.such as airor steam as the casev may be, is supplled to the fluid. chamber 34,

= through, the medium ofthe inclined port 33', 1 the latter giving a whirling action to. the-"=- fluid' and as. the fluid is discharged by the port or passage 49 into the mixing chamber 53, itt horoughly mixes with the oil, at the same t me atomizing' the oil and. theatomized m xture is discharged through the in-.

clinecl ports 53" and directed into. the nozzle i 59, bythe walls ofthe tapering recess 57.

Byforming theoil supply valve 40, integral with the valve stem, which carries the o relative proportions offluid and oil are fed 1 at different openings.

The bore 38,. constitutes a guide for the auxiliary stem 39, while the disk 8 and gland'13 constitute a guide for the valve stem15'. i I ,1 3 Although the element 39 is termed an auxiliary. stem, yet. it is to be. understood vthat it is nothing more than an integral ex; tensionof the valve stem 15'. V 1 i The peripherallythreaded enlarged porwith the threads 9, provides means' .for maintaining the valve stem in the position to Whichit has-been adjusted, I
